Phase Shift Analysis for Alpha-alpha Elastic Scattering using Phase Function Method for Gaussian Local Potential

The phase shifts for α- α scattering have been modeled using a two parameter Gaussian local potential. The time independent Schrodinger equation (TISE) has been solved iteratively using Monte-Carlo approach till the S and D bound states of the numerical solution match with the experimental binding energy data in a variational sense. The obtained potential with best fit parameters is taken as input for determining the phase-shifts for the S channel using the non-linear first order differential equation of the phase function method (PFM). It is numerically solved using 5th order Runge-Kutta (RK-5) technique. To determine the phase shifts for the ℓ=2 and 4 scattering state i.e. D and G-channel, the inversion potential parameters have been determined using variational Monte-Carlo (VMC) approach to minimize the realtive mean square error w.r.t. the experimental data

Evaluating the effect of dexmedetomidine premedication on the quality of subarachnoid block, haemodynamics and sedation in patients undergoing lower limb surgeries: a prospective randomized controlled trial

Background: Present study was designed to evaluate the effect of intravenous dexmedetomidine on haemodynamics, sedation and quality of spinal anaesthesia with 0.5% hyperbaric bupivacaine.Methods: Sixty ASA grade 1 and 2, 18-60 years aged patients scheduled for elective lower limb surgeries were randomly divided into two groups: Group C (Control) and Group D (Study), received intravenous normal saline 10ml and intravenous dexmedetomidine 1μg/kg in dilution of 10ml respectively over 10minutes duration, 10minutes before subarachnoid block with 2.5ml of 0.5% hyperbaric bupivacaine. The heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), quality of sensory and motor block and level of sedation were monitored intraoperatively and postoperatively.Results: The heart rate was statistically significantly decreased in group D both intraoperatively and postoperatively. Intraoperative and postoperative SBP and DBP were lower in dexmedetomidine group but clinically that was insignificant. Intraoperative Ramsay sedation scores were significantly higher in dexmedetomidine group (3.49±0.240) as compared to control group (2.51±0.249) (p<0.001) but the patients were easily arousable. The duration of sensory blockade (208.83±9.53 min vs 162.83±9.62 min), duration for 2 dermatomal regression of sensory blockade (146.5±10.013min vs 98±8.57min) and the duration for motor block regression to Modified Bromage scale 0 (167.33±10.5min vs 137.83±11.94min) were significantly prolonged in dexmedetomidine group as compared to control group. The highest level of sensory blockade was also significantly higher in dexmedetomidine group (T6.90±0.759 vs T7.60±0.621). There was no difference in the time for attaining highest level of sensory blockade, time taken for motor blockade to reach Modified Bromage Scale 3 between both the groups. Average 24hr mean VAS score was significantly lower in dexmedetomidine group (1.37±0.15 vs1.72±0.17, p<0.001). Time to first request for rescue analgesic was also significantly longer in dexmedetomidine group (mean 174.33min vs 143.5min). Average 24hour consumption of tramadol analgesic was significantly higher in control group as compared to dexmedetomidine group (391.86±111.62mg vs 279.86±80.55mg, p<0.001).Conclusions: Intravenous dexmedetomidine significantly prolongs the duration of sensory and motor block of bupivacaine spinal anaesthesia. It provides excellent sedation and analgesia. Dexmedetomidine induced decrease in heart rate, systolic/diastolic blood pressure are not clinically significant.

1′-Ethyl­sulfanyl-1,1′-bicyclo­hexyl-2-one

There are two independent molecules in the asymmetric unit of the title cyclo­hexa­none derivative, C14H24OS, in which both cyclo­hexane rings exhibit chair conformations. They are also equatorial to each other, which permits the ethanethiol substituent to be in a syn conformation with the α-H atom of the parent attached cyclo­hexa­none

Land Use/Land Cover Change and Environmental Impact Analysis of Ramgarh-Naudiha Region in Uttar Pradesh, India through Geospatial Technology

Rapidly changing LULC scenario with growing population is of great concern in the modern world. The present study was undertaken to evaluate the changes in LULC pattern in Ramgarh-Naudiha region of Sonbhadra district, UP, over 20 years during 1998-2018 using datasets from the Landsat Thematic Mapper (TM) 5 and Landsat 8 (OLI/TIRS) satellites. LULC map for the chosen period has been generated by unsupervised classification with maximum likelihood algorithm. Results indicate that the study area is vulnerable to such LULC changes due to its sensitive geographic location. It is found that the major changes did happen in agriculture, forest, wasteland and water bodies. Agriculture and Forest areas have decreased by similar to 2 and 6.56% respectively in the study period. The wastelands had increased fast from 5.08% in 1998 to 18.87% in 2018 at the cost of the forest cover and agricultural land respectively. In 1998, water bodies were 7.49%, whereas, it has decreased to 2.04% in 2018. On the contrary, urban fringe area has grown from 0.33% in 1998 to 0.49% in 2018 especially due to population growth. The present study concludes that this LULC analysis will increase awareness and help in taking necessary action in appropriate land use planning and management

CURRENT UPDATES ON ANTI-DIABETIC THERAPY

ABSTRACT Diabetes globally has become one of the chronic public health problems and is related to group of metabolic defects resulting due to defect in insulin secretion and its action. As the disease progress micro and macro vascular damage may lead to retinopathy, neuropathy, nephropathy and various cardiovascular like complications. It is estimated that by the year of 2030 about 439 million adults would be suffering from any form of diabetes. There are mainly two types of diabetes which is because of their occurrence rate. The current review covers the basic aspect of types of diabetes, insulin molecular, chemical basis, and its secretion, hypoglycemic drugs used and their mode of action, what are the recent advancement in terms of new drugs finding, and the herbal plants.

Assessing the Impacts of Tillage and Mulch on Soil Erosion and Corn Yield

Conventional tillage practices have been regarded as the major reason for the loss of fertile topsoil in the sloping agricultural lands of the middle hills of Nepal. Reports on the effects of no-till and mulch on soil and corn yield in these regions are scarce, although these farming practices have been recommended to reduce soil erosion and increase crop yields. To assess the impacts of tillage (with +T, without −T) and mulch (with +M, without −M) on soil and soil nutrient losses, and corn yield, we conducted an experiment with five treatments: −T+M, −T−M, +T+M, +T−M, and bare fallow (BF), replicated four times each in an unbalanced complete random block design in Salyan district of Nepal. The results showed the presence of corn and no-till significantly lowered the soil losses. Losses of soil organic matter (SOM) and total nitrogen were also significantly reduced by the presence of corn, no-till, and mulch. However, no effects of mulch on soil losses, and no effects of tillage, mulch and corn on soil phosphorus losses were observed. Soil loss was found to be significantly and positively correlated with total seasonal rainfall, monsoon being the most severe season for soil erosion. While no-till and mulch did not affect corn height, cob height, and stover yield, no-till significantly increased the corn yield by 0.52 Mg ha⁻¹ compared to conventional till. We confirm the synergistic interaction of mulch with tillage to reduce the losses of SOM and total nitrogen, and effectiveness of no-till to reduce the soil losses and increase the corn yield in the middle hills of Nepal. As this study is based on the results of two year’s data, long-term studies are required to identify the long-term impacts of no-till and mulch on soil losses and corn yield across the country

Hairy cell leukemia : experience at a tertiary cancer centre in Northern India

Background : The prognosis of Hairy cell leukemia (HCL) has improved markedly following treatment with cladribine (2- CdA), a nucleoside analogue. We reviewed data on patients with HCL treated in our department. Methods . Between 1995 and 2004, 23 patients with hairy cell leukemia (HCL) were diagnosed Patients median age was 48.5 years (range, 32 to 66 years), there were 18 males and 5 females. The common presenting symptoms were: fatigue (82.6%), fever (34.7%), abdominal discomfort (21.7%), arthralgia/bone pains (13%) and bleeding (17.3%). 22 of 23 (95.6%) patients had enlarged spleen, and hepatomegaly (65%). Lymph node enlargement was present in 17% of patients. Investigations revealedmedian Hb of 7.8g% (5.7 to 12.9 g%), thrombocytopenia (median 55000/cmm) and median WBC count of 3500/cmm (range, 600 to 20,200/cmm). Bicytopenia or pancytopenia was present in 87% and bone marrow fibrosis in 75% of cases. Immunophenotyping studies revealed expression of CD11C (60%), CD25 (60%), FMC7(47.8%), CD23(34.8%), CD103 in 39% of cases. 20 of 23 patients received treatment; two received treatment else where and one patient died of liver failure prior to treatment. 17 of 20 patients were treated with 2-CdA, 2 with interferon alfa (IFN-a) and one patient underwent splenectomy alone. Three patients received 2-CdA as second line therapy for treatment of relapse: this includes . one patient each, treated with IFN- α and splenectomy both and one patient received 2-cdA twice in view of relapse. Results . Following treatment with 2CdA . 95% of patients responded; complete-84.2% and partial response in 10.5%. one (5.2%) patient died of toxicity. Two patients relapsed at a mean follow up of 25 months. The common side effects were febrile episodes (n=10) and grade I-II myelosuppression. One patient died of toxicity to 2-CdA. This patient was a known case of multidrug resistant disseminated tuberculosis. He had severe myelosuppression with fungal sepsis with multiorgan failure and BM Aspirate was positive for AFB. Other infections documented were Pulmonary tuberculosis in 2 and herpes zoster in one patient. The patient who underwent Splenectomy achieved remission but relapsed after 3 years and was salvaged with 2-CdA again. Median time for normalization of blood counts after 2-CdA was 28 days and median time to regress spleen was 41.5 days . Conclusion . Present study confirms good outcome with 2-CdA (cladribine) therapy for patients of hairy cell leukemia
